I just upgraded from Snow Leopard to Mountain Lion and I seem to be missing one bit of functionality that I used all the time in Finder. I could press Command+Shift+F and search for files by file name. Now pressing Command+Shift+F takes me to the "all my files" folder.

The UI is broken. You do not have to select the "name matches" option, it is simply the default and automatically selected when you hit enter. Instead, you can click away from it resulting in identical UI for both search methods, but one does in fact search the names only. Demo screenshot: i.imgur.com/GJt9qQp.png (10.8.2)
